<Summary of Head Mounted Display>

First, based on FIG. 1, the outline of the head mounted display 100 which is one Embodiment of this invention is demonstrated. FIG. 1 is a diagram showing a schematic configuration of the head-mounted display 100.

The head-mounted display 100 is a display device that can be mounted on the head of a user. Also, as shown in FIG. 1, the head-mounted display 100 is a binocular type and is an immersive type head-mounted display that completely covers the eyes of the user in a state of being attached to the head. The same applies to the head mounted displays 200 and 300 described later.

Specifically, the head-mounted display 100 has an image display unit 2 (display unit) in the housing 1. The display screen of the image display unit 2 includes a plurality of pixels written with image data, and the transmission amount of light radiated from a backlight (not shown) arranged on the back of the image display unit 2 changes for each pixel, thereby The image I shown in the image data is displayed on the display screen (refer to FIG. 3). In addition, in this embodiment, the case where one display portion (image display portion 2) is provided in the case 1 will be described as an example, but the head-mounted display of one aspect of the present invention can also be applied to the case provided in the case Head-mounted display with multiple display sections. Alternatively, it is also envisaged for applications without a backlight, such as organic EL displays.

In addition, the inside of the housing 1 is partitioned by the first light guide plate 5, and a right-eye lens 3 a (lens) is arranged in a region facing the right eye of the user of the first light guide plate 5. On the other hand, a left-eye lens 3b (lens) is arranged in a region facing the left eye of the user of the first light guide plate 5. The right-eye lens 3a is a lens for the user to view the image I displayed on the display screen of the image display unit 2 with the right eye, and the left-eye lens 3b is the user for viewing the image display unit 2 with the left eye The lens showing the image I of the screen. The first light guide plate 5 guides the light radiated from the LED 4 described later to the periphery of the right-eye lens 3a and the left-eye lens 3b.

Moreover, LED4 (light emitting part) is arrange|positioned at the edge part of the 1st light guide plate 5 in the short side direction, respectively. Since the LED 4 is disposed on the end portion on the right-eye lens 3a side, the periphery of the first opposing surface 3a-1 (opposite surface) facing the user's right eye in the right-eye lens 3a is radiated from the LED 4 Light irradiation. In addition, since the LED 4 is disposed at the end portion on the left-eye lens 3b side, the left-eye lens 3b is radiated around the second opposing surface 3b-1 (opposite surface) facing the user's left eye Light from LED4 Irradiation. The colors of the lights radiated from the two LEDs 4 are adjusted by the emission color determination unit 10 described later.

In addition, the arrangement and number of the above-mentioned LEDs 4 are only examples, as long as they can illuminate the periphery of the first opposing surface 3a-1 of the right-eye lens 3a and the periphery of the second opposing surface 3b-1 of the left-eye lens 3b , The arrangement and number of LED4 can be changed arbitrarily. Moreover, other light sources can be used instead of LED4.

In addition, a plurality of LEDs 4 in which the analysis target area to be described later should be set in a wider range can be arranged at desired positions inside the casing 1. In this way, the user can obtain a stronger sense of immersion and presence. In this case, depending on the number of LEDs 4, it is possible to illuminate the periphery of the first opposing surface 3a-1 of the right-eye lens 3a and the second opposing surface 3b-1 of the left-eye lens 3b only by the light of the LED 4 Around, no first light guide plate (not shown) is required.

In other words, since multiple (plural) LEDs 4 are provided inside the housing 1, only the multiple LEDs 4 emit light, around the first opposing surface 3a-1 of the right-eye lens 3a and the left-eye lens 3b The periphery of the second opposing surface 3b-1 is irradiated with light emitted from the LED 4.

<Functional configuration of head-mounted display>

Next, the functional configuration of the head-mounted display 100 will be described based on FIGS. 2 and 3. FIG. 2 is a functional block diagram showing the functional configuration of the head-mounted display 100. FIG. 3 is a diagram showing an example of analysis target regions F1 and F2 in the video I displayed on the video display unit 2.

As shown in FIG. 2, the head-mounted display 100 includes a control unit 20. The control unit 20 is a circuit that controls each part of the head-mounted display 100 in a unified manner. In addition, the control unit 20 generates video data for display on the display screen of the video display unit 2. The generated video data is temporarily stored in the VRAM (Video Random Access Memory) 21 provided in the control unit 20. Then, the image data is read from the VRAM 21, and the image data is transferred to the image display unit 2 at a predetermined time.

The image data is transferred from the VRAM 21 to the image display section 2, the image data is written to the display screen of the image display section 2, and the image I (refer to FIG. 3) is displayed on the display screen.

Furthermore, the control unit 20 controls the writing operation of the video data of the video display unit 2 or the turning on/off of the backlight. However, such operation control may be performed on the image display unit 2 side.

Furthermore, the control unit 20 may be built in the head mounted display 100, or may be an external device mounted on the head mounted display 100. For another example, the control unit 20 may be a network server used through a communication unit (not shown) included in the head-mounted display 100.

In addition, the control unit 20 includes a color analysis unit 6 and a light emission color determination unit 10 (both are light emission color adjustment units). The color analysis unit 6 analyzes the color of the video I displayed on the display screen of the video display unit 2. Specifically, the color analysis unit 6 reads the image data of the image I stored in the VRAM 21, and decomposes the colors of the dots corresponding to the image data of the image parts constituting the analysis target regions F1, F2 into the image data into RGB components. Then, for each of the above points, the brightness values of the color components (R component, G component, and B component) are measured to analyze the color of the image data of the image I. The analysis result is sent to the emission color determination unit 10.

Here, the analysis target regions F1 and F2 refer to specific regions in the image I that are the analysis targets when the color analysis unit 6 analyzes the image I. In the present embodiment, as shown in FIG. 3, the end region toward the right side of the paper in the video I becomes the analysis target region F1, and the end region toward the left side of the paper becomes the analysis target region F2. In addition, the analysis target regions F1 and F2 shown in FIG. 3 are only examples, and the analysis target regions of appropriate and appropriate positions, shapes, and sizes can be set according to the relative positions of the lens and the light source (light emitting part) or the number of light sources .

The light emission color determination unit 10 receives the analysis result of the color of the image I displayed on the display screen of the image display unit 2 and determines the color around the screen as the color of the light emitted by the LED 4 based on the analysis result. Specifically, the light emission color determination unit 10 receives the solution from the color analysis unit 6 As a result of the analysis, for the image data corresponding to the image parts constituting the analysis target regions F1, F2, the sum of the brightness values of the color components of each point is calculated for each color component. Then, the average value is calculated by dividing the sum of the luminance values of the above color components by the number of points, and the light emission color determination unit 10 determines the color represented by the combination of the average values of the luminance values of each color component as the surrounding color of the screen. Furthermore, the emission color determination unit 10 controls the lighting of the LED 4 so that the color of the light emitted from the LED 4 becomes the color around the screen.

The light emission color determination unit 10 and the color analysis unit 6 constitute a light emission color adjustment unit according to an aspect of the present invention. The light emission color adjustment unit analyzes the color of the image I displayed on the display screen of the image display unit 2 and adjusts the color of the light emitted by the LED 4 according to the analysis result.

In addition, the method of determining the surrounding color of the screen by the light emission color determination unit 10 is not limited to the above-mentioned case. For example, the light emission color determination unit 10 may calculate the frequency value of the color value corresponding to each point of the image part constituting the analysis target regions F1, F2 by the histogram, and express the color represented by the brightness value with the highest frequency value Decided as the color around the screen. In this case, for example, the range of the brightness value of ±5 is set as the calculation target, and the median value is set as the frequency value.

In addition, it is not necessary to adjust the color of the light emitted by the LED 4 by the emission color determination unit 10 or the like. At a minimum, it is sufficient to irradiate the periphery of the first opposing surface 3a-1 of the right-eye lens 3a and the periphery of the second opposing surface 3b-1 of the left-eye lens 3b with light emitted from any light-emitting portion.

<How to light the LED with colors around the screen>

While the image data of one frame stored in the VRAM by the control unit 20 is transferred to the image display unit 2 (step S101: the step is omitted below), the color analysis unit 6 analyzes and displays on the display The image data of the image I of the screen corresponds to the color of the image data of the image parts of the analysis target areas F1, F2 (S102). The analysis result is sent to the emission color determination unit 10. Here, the image data of the I frame refers to the image data of one time displayed on the display screen of the image display unit 2.

Next, the light emission color determination unit 10 that has received the analysis result determines the surrounding color of the video (S103), and lights the LED 4 so that the color of the light emitted from the LED 4 becomes the surrounding color of the screen (S104). The processing of S101 to S104 is repeated a number of times of a predetermined number of frames, whereby the surroundings of the first opposing surface 3a-1 of the right-eye lens 3a and the first of the left-eye lens 3b are irradiated with the color light around the screen Around the two opposing surfaces 3b-1, one side displays all image data on the above display screen.
